To all whom it may conceive:

Be it known that l, RICHARD E. Moore, 21

citizen of the United States, residing at- Agency, in the. county ofBuchanan and State of Missouri, have invented certain new and usefulImprovements in Screen Doors, of which the following is a specification.

' This invention relates to screen doors and its object is to provideinexpensive means whereby sagging of the door or warping of a stile willbe prevented, the invention seeking to provide means for the statedpurpose which will be light, easily applied. and durable. The inventionis illustrated in the accompanying drawing and "will be hereinafterfully set forth.

in the drawing:

Figure l is an elevation of a screen door having my improvements appliedthereto;

Fig. 2 is an edge view of the door;

Fig. 3 is an enlarged longitudinal section or one of thestretchers andits mounting;

Fig. 4 is an enlarged elevation of one of the truss bearings and guides;v

Fig. 5 is a perspect ive of one of the guides, and

Fig. '6 is a perspective of an anchoring member.

The door 1 may and is mounted in be of any preferred form the usualmanner. Along .the free stile 2 of the door, "I secure a plurality oitruss members 3 which, as shown mOSt clearly in Fig. 5, consist ofsimilar metellic plates 4 shaped to produce a sleeve or eye 5 at theouter ends of supporting webs the webs being spread laterally, as shownat 7, whereby they may rest flat against the stile and be securedthereto by screws or similar fastening de vices. Obviously, the sleevemay be free of joints and constitute a connection between the outer endedges of the webs. I find it to be advantageous, however, in making andassembling the parts of the invention, to form a half sleeve on each weband secure them in mating relation by inserting a rivet 8 through thewebs. The base plates or feet 7 are somewhat tapered and terminate inspurs 9 which may easily penetrate the stile to aid in maintaining thebearing in place, openings 10 bein provided in the feet to permit theinsertion of the securing screws or nails. As shown most clearly in Fig.2, the supporting webs 6 of the several truss bearing members are ofdifierent lengths, the central member having the greatest length orheight and the other members being successively reduced in height sothat a tension wire 11 inserted through and carried by the severalsleeves or eyes 5 will be given an arched or trusslike form, as shownclearly in Fig. 2, to

counteract any tendency of the stile to warp.

One end of the tension wire 11 is connected to an anchoring memberconsisting 'of a plate 12 having one e e notched and rolled upon itselfwhereby to provide elined bearings 13, and a bail or clevis 14 havingits terminals 1.5 spread laterally to be engaged in the said bearingsleeves 13, as shown clearly in Fig. 6. lhe end of the tension wire iswrapped around the shoulder or bridging member of the bail, between thesides thereof, and may be tiedthereto in any approved manner. Theopposite end of the tension wire is connected with a stretcher ldwhichconsists of e metallic-plate or strap bent midway its ends to provideparallel side portions 17 and a bridging member'lS connecting the saidside portions. The free ends of the side members are perforated, as

shown at 19, to receive the hooked ends 20 of a clevis or bail 21, theupper end of the tension wire being wrapped around and tied to theshoulder or lower end of the clevi s. The bridge portion 18 of thestretcher is disposed egainst' the stile and is held thereto .by a

bracket consisting of a. bar or strip of sheet metal having its endportions bent vto define feet 22 to be attached to the stile, and

a bridge member 23 extending longitudh nally of the stile and held inspaced relation thereto by the webs 24 connecting thesaid bridge withthe feet 22. The webs 24care provided with suitable openings in which ismounted on adjusting screw 25 having its ends swiveled in the webs andits intermediate portion passing through a corresponding opening 1n thebridge member 18 of the stretcher. A nut 26 is engaged with the screwbetween the lower end of the bracket and the bridge piece 18 of thestretcher and bears'against the said bridge, the out being preventedfrom turning by the engagement of its sides with the bridge member ofthe bracket and the sides of the stretcher. One end of the adjustingscrew is suitably constructed to be engaged by a. turning tool, and itwill be readily seen that rotation of the screw will cause the nut toride longitudinally upon the Screw" and thereby shift the stretcherlongitudinally place the wire8 under any desired member 28 correspondingin all respects to the anchor 12. At the upper corner of the door, abracket 29 is secured to the hinge stile 30 thereof, and a stretcher 31is en gaged under the said bracket, as, shown in Fig. 1. The bracket 29corresponds in all respects to the bracket 22, 23, and the stretcher 31corresponds in all respects to the stretcher 16. A' tension wire 32 issecured. to a1" ntends between the anchor 28 and the stretcher 31, andis put urn der proper tension by adjustment 0d the said stretcher sothat it tends to resist and overcome any sagging tendency which maydevelopin the door. Theihandle 27, as shown in Figs. 1 and 2,, isprovide-d with terminal feet which rest against and are secured to thestile and the dividin bar .re-

spectively of the door, and one toot rests upon the-anchor 28, a singlefastening screw or nail serving to secure bothelements in lace. P Itwill be readily seen that I have provided exceedingly inexpensive andeliicient means for preventing sagging or warping of a screen door andthat the devices of the invention may be easily applied to the door byan unskilled person and, when applied,

will operate in a highly eiiicient manner.

The present construction minimizes the number of parts, therebysimplifying the manufacturing processes and reducing cost. The tensionwires are preferably two strands twisted together and are soillustrated.

Having thus described the invention, 1 claim:

1. Means for the purpose set forth com prising an anchor member, abracket spaced from the anchor member and comprising end attachingportions and an intermediate bridging portion, a stretcher comprisingparallel side members embracing one end portion of the bracket and anend member connecting said side members and slidably engaged under thebridging portion of the bracket, a tension member engaged at (me endwith the anchoring member and at its inner ends minals engaged in thebearings, a stretcher, v

means for adjusting the stretcher and socur ing it in a set position,and a tension mem ber secured at one end in said bail and at itsopposite end to the stretcher.-

3, Means for the purpose set forth comprising an anchor plate providedat one end with alined bearings, a bail disposed between said bearingsand having lateral terminals engaged in the bearings, a stretcher, meansfor adjusting the stretcher and secur .ing it in a set position, atension member socured at one end in said bail and at its opposite endto the stretcher, and a plurality of alined sleeves disposed between theanchor and the stretcher and encircling and supporting the tensionmember, the sleeves being in stepped relation from the central sleeve tothe end sleeves.

4. Means for the purpose set forth comprising an anchor plate providedat one end with alined bearings, a bail disposed between said bearingsand having lateral terniinals engaged. in the bearings, a stretcher,
